Chapter 323 Give me a sample so I can examine it
Gao Zhendong took out two drawings, one as deep as a funnel and the other as shallow as a plate. "Go to the warehouse and get the test materials marked WT-1 and WT-2. Find Master Yi Zhonghai and process 10 of each material according to the drawings. Do not use cutting, milling, drilling or other processes. Just tell him that these will eventually be stamped parts, and he will naturally understand how to do it."

Those who know the business can tell what this thing is by looking at its shape, at least they can recognize one of them, but Liu Rongguo doesn't recognize it.

Even though he didn't know the person, it didn't stop him from doing his job. He just responded, took the money and left. He didn't ask questions that he shouldn't ask. He understood this principle.

Gao Zhendong wanted to see if he could change the material of the medicine cap.

The most common material for the liner is red copper, but that doesn’t mean it is the best. It is common because it is cheap.

If you insist that copper is not cheap, then if you give an example of a material that is more suitable than copper in terms of price alone, you will understand what expensive means.

As the material responsible for generating the metal jet to penetrate the armor, it should have high density, high dynamic elongation at break, good sonic performance, and good thermal conductivity.
Note that, contrary to what you might think, hardness is not that important when it comes to armor-piercing shells.

When you see this, do you remember anything?
Oh, that’s right, gold!!

Gold coin bomb. Really!!

If Gao Zhendong dared to suggest using this thing to make charge hoods, I'm afraid the leaders of the 17th Ministry of Machine Building and the Defense Work Committee would jump up and clean his ears.

But when it comes to tungsten copper and the like, there is something to say. Although tungsten copper also has defects, it is better than copper in terms of potential, and we have a lot of tungsten.

Forget about tungsten-molybdenum alloy, which theoretically has potential, but it is enough to work with tungsten-copper first.

“Ding-ling-ling~~~~~~”

Gao Zhendong, who was working, answered the phone. On the other end of the line was Zheng Liangshu's voice.

"Lao Gao, good news. We have already produced one of the three types of steel you gave us and delivered it to Beijing University of Technology. They tested it and were full of praise for the steel's performance!"

Zheng Liangshu's opening words were good news. For him, with this one, this year's KPI would be stable. If the other two could be achieved, it would be pure profit.

He even felt a little regretful. It would be better if one of these three could be kept until next year, so that there would be a long-term benefit.

I turned around and almost slapped myself. What are you thinking about?

Gao Zhendong was delighted when he heard this. It's not that this thing has any significant significance. Compared with his other achievements, this thing is just average. However, it's a knife, now he can have a good knife to play with. Hehe, any man would find it interesting.

"Great, give Beijing University of Technology a call and ask them to give me a copy of all the samples they are researching."

Zheng Liangshu knows everything about the matter. He will leave you a sample. You are just itching to try it. Haha.

The two laughed and chatted for a while, and Gao Zhendong said, "Old Zheng, this steel has both hardness and toughness, and it is also weather-resistant. You can look for agricultural and mechanical ones, and ask for recommendations."

For example, it can be used as a hoe or a plowshare. It is really useful.

Don't talk about the soil, just farm the land, be serious about it.

Don't say it's expensive. If this type of steel is classified based on materials and craftsmanship, it is just ordinary goods. There is no expensive one, provided that the output is not too small.

I was a little confused by Gao Zhendong's big step. Damn, good job, Gao, your thinking is quite flexible.

Zheng Liangshu, who came from a political work background, understood the meaning of Gao Zhendong's words very well.

If the military industry is about defending the country, then Gao Zhendong's suggestion just now is about serving the people, promoting production, increasing output and income. The significance of this is even higher.

"Okay, okay, Lao Gao, this is a good idea. I'll do it right away, haha." He agreed readily. This was not false exaggeration. He really had good stuff in his hands, so there was nothing to be afraid of.

This is also Gao Zhendong's purpose. This kind of steel must have other uses, but Gao Zhendong has never studied what they are used for, nor does he have the leisure to study them. Wouldn't it be great if he could just mention it to Lao Zheng and let him take charge of this matter?

In this matter, everyone has a bright future.

The two chatted for a while and then hung up the phone. Before hanging up, Zheng Liangshu laughed and said, "I'm going to try the second one, hahaha." His laughter was very contagious. With the success of the first one, his confidence in the latter two was simply overflowing. It felt like he had found them by chance.

At Beijing University of Technology, a student excitedly went to find his teacher with a test record.

"Professor Liu, the test results of the new spear are out! Very good!"

Professor Liu, who was previously responsible for communicating with Gao Zhendong, took the test record, pushed his glasses up his nose, and looked at it carefully.

There is a relatively clear statement that the early domestic bayonets eventually evolved into a structure similar to the Type 53 four-sided bayonet, with the only difference being three-sided and four-sided. The biggest reason for this is the metallurgical problem. Once it is made too long, it lacks rigidity and is prone to bending.

Easy to bend here means that it will not recover after being bent. It will bend when subjected to force, but it will not work if it does not recover after being bent.

It is not known whether this statement is correct, but there must be a reason for abandoning the blade and making it a single function for stabbing. Anyway, Gao Zhendong has solved the steel problem this time, and it depends on the designers how it will be designed.

And there is a side example. Taking the 56 and a half as an example, there are two common bayonets. One is a rib bayonet and the other is a dagger-shaped bayonet. Although both are folding, the length of the dagger-shaped bayonet is much shorter than that of the rib bayonet.

It can be seen that the influence of materials on length is still obvious. Otherwise, according to the combat thinking at that time, the distance advantage of stabbing would not be given up, or in other words, in order to gain the distance advantage of stabbing, the ridged thorn was finally used. Professor Liu looked at the test record and praised it repeatedly.

"Good. The rigidity, toughness, and corrosion resistance are all very good. The bending resistance is also very good. This thing is good. We can rest assured about the bayonet. We just need to make minor repairs based on the feedback."

"Professor Liu, Director Gao said that he wants to see some bayonet samples."

Professor Liu, who was old and clever, could guess a little about Gao Zhendong's idea. He laughed and said, "Well, that's no problem. Bring us a handful of our trial products and we'll go visit him."

Sending samples is a small matter. The reason why Director Gao wanted samples is just that.

The main issue is the design of the firearm, which has reached a certain level. We should also communicate with Director Gao so that any problems can be discovered and resolved early.

Although the theory is good, when it comes to practice, I still have to find a killing god who has emerged from the battlefield and listen to his opinions.

Moreover, Director Gao is not necessarily worse than us in theory. The opinions put forward by such comprehensive people are often of great significance.

When I saw Gao Zhendong, he was in his office, drawing something.

Seeing Professor Liu and others coming, Gao Zhendong put away his things and was excited. The bayonet samples are coming?
Sure enough, after Professor Liu sat down, he took out a nearly 40-centimeter-long thing from his pocket and handed it to Gao Zhendong.

"Director Gao, this is the bayonet for the new gun we are trying to make using the new steel you researched. Take a look and give me some suggestions."

Gao Zhendong took it with joy, pulled out the bayonet from the scabbard, and looked at it carefully with a happy expression on his face.

How to put it? Maybe it was because he was used to seeing short bayonets and long bayonets in his previous life, so Gao Zhendong felt uncomfortable looking at this long bayonet.

A length of nearly 40 centimeters may not sound too long, but if you compare it, you will know the length. This thing is nearly half the length of an AK-47.

It is said to be multifunctional, but it is obvious that the people from Beijing University of Technology have not thought so much about "multifunctional". They just make serrations on the back of the knife, and think it is multifunctional.

Don’t tell me, just tell me whether it has too many functions or not.

Probably, you can imagine this multifunctional bayonet as a Type 38 bayonet with a serration on the back of the blade.

This made Gao Zhendong, who originally just wanted to collect it, a little nervous. You want to ask if this thing is a bayonet? Is it a multifunctional bayonet?

What he didn't know was that the few trial production quantities of this thing would later become treasures in the military collection world. The reason was that the quantity was small and the significance was great. After all, there were not many opportunities to see the dark history of Beijing University of Technology, and this thing was one of them.

No, it needs to be changed. This thing has been accepted, but the bayonet still needs to be improved.

Seeing Gao Zhendong's constipated face, Professor Liu asked, "Director Gao, what about this knife?"

Gao Zhendong came back to his senses: "Ah, ah, the knife is not bad, not bad."

Professor Liu saw his expression and knew that Director Gao was reluctant to discourage his enthusiasm, so he simply said, "Director Gao, if you have any ideas, just tell me. It's okay. We are still in the design stage. We are here to listen to your opinions."

Gao Zhendong nodded and said, "You asked me to say it."

"In this way, I think it can at least add the functions of filing and cutting. In addition, it would be nice to make the whetstone directly on the scabbard."

Professor Liu thought about it and felt that Director Gao’s idea was the exact opposite of “making the bayonet multifunctional”. It was “making a multifunctional knife that could also be used as a bayonet”.

This idea seems to be good. It is a way to go. Let’s give it a try.

"Director Gao, please tell me in detail. I might as well just be a plagiarist today, haha."

Gao Zhendong directly recounted the results of imitating the Citigroup M9 in his previous life, including the shear blade, shear plate seat, shaft hole, file tooth area, flat edge and so on.

He added: "This knife is relatively long, so the hardening treatment of the scabbard can be done only on the lower half."

If the scabbard is not hardened, then the scissors will not be able to exert much force.

Professor Liu feels that although these suggestions are simple, they can really solve many problems. For example, cutting barbed wire is something that will always be needed, even decades later.

He wrote down the notes one by one with satisfaction. Well, this time the design of the bayonet was complete.

Then, he took out another thing: "Director Gao, this is the result of our firearm design so far, please take a look."
